v2.0.0

Spin v2.0.0 🚀

We are excited to announce the release of Spin 2.0! This is the latest major release of Spin
which focuses on improving key scenarios for running WebAssembly applications.

What's new 💅

• Component support

  Spin 2.0 now supports running composed WebAssembly Components.
  Dive into the examples mentioned below for a demonstration of this functionality.

• Polyglot

  Thanks to composition, Spin application developers can build polyglot applications incorporating components
  built from any language with support for compiling into a WebAssembly component.

• Portability

  Spin has now standardized on wasi-http. This means components
  built by Spin can be run by other runtimes supporting the same wasi-http version.

• Performance

  Spin 2.0 brings a big performance boost, utilizing wasmtime's pooling allocator and no longer
  copying Request and Response bodies. In some cases, we've seen 10x the performance when compared to Spin 1.0!

  Note: For Linux hosts, there is a known pending performance fix in wasmtime#7475
  that will be ported to Spin as soon as available.

Check out the examples 👀

• Dive into the Http Auth Middleware example for a demonstration of
  using component composition to integrate an http auth middleware component into a Spin application.

• Experimental streaming support also ships in this release, enabling a whole new suite of scenarios for Spin
  application developers. See the Spin fileserver component for an example using this functionality.

Breaking changes ⚠️

• OCI distribution: We've updated the way we distribute Spin apps to enable upstream scenarios
  such as containerd and Kubernetes. This means pre-2.0 Spin clients won’t be able to pull or run Spin apps published by 2.0 Spin clients
  • Fix: update to the 2.0 version of Spin
• spin new / spin add - syntax is now spin new -t <template> <name>.
  • spin new <template> no longer works; however, spin new and spin new <template> <name> still do
• C# templates won’t work with Spin 2 yet (more generally, templates with custom filters won't, but to our knowledge C# was the only one)
• v2 SDK and manifest related changes:
  • After upgrading to use the v2 manifest,
    applications which use Postgres, MySQL or outbound Redis must provide an allowed_outbound_hosts configuration
  • Multiple Rust API changes: outbound HTTP, outbound Redis, application variables
  • Go has a new API for Redis
  • Go key_value package has been renamed to kv and has a new API

Highlights since Spin 1.0 ✨

Here are some highlights you may have missed that shipped in the releases between 1.0 and 2.0:

• DevEx/CLI
  • spin watch to automatically rebuild and restart
    you Spin application when files change
  • spin doctor to detect and fix issues with your Spin application
  • All spin cloud commands now ship via the Spin Cloud Plugin which is automatically installed when you install Spin
• Persistence/Data services
  • Key Value Storage
  • SQLite Storage
  • Serverless AI
• Runtime improvements
  • Enabling wasmtime's pooling allocator for increased performance.
• Language support
  • Python SDK
  • Go SDK adds support for outbound MySQL and Postgres

Thank you! ❤️

As always, many thanks to contributors old and new for helping improve Spin on a daily basis! 🎉 The 2.0 release represents
a huge milestone for the Spin project and we couldn't have done it without you.

Spin v1.3.0

We are excited to announce the release of Spin 1.3! The v1.3.0 release of Spin brings a number of features, user experience improvements and bug fixes. It also highlights work to focus the scope of the core Spin CLI as the cloud deploy and cloud login subcommands were removed from Spin and moved to the new cloud plugin. Users who wish to log into or deploy to Fermyon Cloud will have the same experience as before. When you run spin cloud login or spin cloud deploy in Spin 1.3, Spin will look for the cloud plugin, and if it is not installed, it will install it for you.
